The River Modeling Flume was built in 2001 as part of a collaborative CFI grant with the Faculty of Engineering to fund the development of new space for physical experiments related to environmental fluid dynamics: the Newalta Environmental Fluids Laboratory, located in the Boundary Layer Wind Tunnel Building. The 3m x 20m tilting river tray was designed for the physical modelling of gravel-bed rivers and can also be used for the study of other problems in river morphology, river restoration, open-channel flow and sediment transport. It is the largest tilting, river modelling flume in Canada, and has attracted collaborators and students from Canada, U.S., Israel, France and Italy.
